Loops from Logic Pro - copy to Logic Pro X

Yes, and you won't even need your LP9 installation DVDs to install Legacy content. Just go to Logic Pro X > Sound Library > Open Sound Library Manager > Legacy and Compatibility. There're all Jam Packs available (i.e. Apple Loops and Sampler Instruments collections) from previous versions of Logic.

No worries, glad to help. In theory, it should still be possible to install the loops manually. Installation packages are on LP9 DVDs, you just need to find a way to extract them to your Mac's HD somewhere and then install them one-by-one.
